中文摘要：

钛及其合金以其良好的耐蚀性能、机械性能和生物相容性,被广泛应用于牙科领域;口腔是一个极其复杂的微生物环境,微生物对钛及其合金的腐蚀影响不可忽视。综述了几种常见口腔微生物对钛及其合金的腐蚀研究现状,探讨了钛材在口腔环境中的腐蚀机理,并对钛及其合金的口腔微生物腐蚀研究趋势进行了展望。

英文摘要：

Titanium and its alloys are widely used in dental fields due to their excellent corrosion resistance,mechanical properties and biocompatibility.Oral cavity is an extremely complex microbial environment,the effect of microbial corrosion on titanium and its alloys in oral cavity can not be ignored.The latest microbial corrosion research developments of several common oral bacteria are reviewed,and the related corrosion mechanisms are discussed,additionally,the possible research trends for oral microbial corrosion of titanium and its alloys are suggested in this paper.
